How 'bout we agree to disagree? People love to argue and I doubt online arguments are ever REALLY resolved.
I asked what color the parents are, because regardless of foal coat colors that information will be a big help in determining what color the foal is. And, I didn't have to imply anyone was stupid. But, I can see how with over population and ill educated breeding some people can be quick to judge and quick on the offensive. So....
On to the baby...
To talk about strange colors and genetic business like sooty buckskins, grulla, chocolate, silver, etc. You need happy appy help. But, judging soley from the picture I'd say bay. Roan foals are born roan, they don't fade to roan like greys fade to gray. However, appy's can tend to change coats a bit as they age and shed. You never know what new spots an appy may get when he sheds to his summer coat.
Also, the mare (?) in the picture with the foal is not a roan, just in case that is momma.
